BALL-BEARING.

Specification of Letters Patent.

Original application filed April 27, 1912, Serial No. 693,735. Divided and this application filed February 26, 1913." Serial No. 750,876. i

To all whom it may concern:

Be it known that 1, Swan GUSTAF WING oursr, a subject of the King of Sweden, residing at Gottenborg, Sweden, have invented certain new and useful Improve ments in Ball-Bearings, of which the following is a specification. r

The present application is a division of my application No. 693,735, filed April 27, 1912.

The principal-object of the invention is to provide a sheet metal retainer for ball bearings, weight, can be manufactured easily and sold cheaply, and the balls can be readily located within and withdrawn from the same.

Other objects of the invention will hereinafter appear. I

One feature of the invention consists in the ring being curved or shaped as a cup opposite to and substantially inclosing'each ball.

The invention further comprises other constructions and combinations of parts which are described hereinafter.

The accompanying drawings show a plurality of forms of the retainer.

Figures 1 and 2 are respectively a diametrical section and an edge view of one style of retainer embodying the invention; Figs. 3, 4 and 5 are respectively a diagrammatic face View, a diametrical section, and an edge view, showing another style of retainer embodying the invention.

The retainer consists of a ring 1 of sheet metal, which is located at one side of the set of balls 2, and iscurved in cross-section in accordance with the curvature of the balls. The ring is so shaped that it forms a cup at each ball, conforming to and engaging the balls at all sides except the sides in contact with the races, and sub' stantially or approximately inclosing the same. For example, as illustrated, the outer and inner portions 'of the ball Qalong a radial line of the bearing) are free to be engaged by the ball races; and the retainer engages the balls at the front and rear and also at the sides. In this construction the cup shape is carried to such a degree that the bottom of the cup, viewed from the edge so arranged that it is-of lightof the ring, in the direction of the radius of the ring, forms substantiall a semicircle or more than a semicircle. he cup is indicated by the numeral 6. The lips are extended axially ina suitable curve, and both lips preferablyuniformly and to such a degree that the edges practically or nearly meet. I

The lips may belben't transversely, that is in a direction transverse to the axis of the bearing, independently'of a greater or less depth of the cup'6, so that the flat face of the sheet metal forming the lips engages the side of the balls which the lips fit more or less closely. This arrangement is shown in two slightly different forms, first in Figs.

1 and 2, and second in Figs. 3, 4 and 5,; the lips being designated by the numeral 7.

through the center points of the balls; the.

edges of the retaining ring thus bent inward serving to keep the balls at their proper distances apart, without the necessity of using thick material for thering. In fact the ring is preferably made of, thin material so that its parts which are bent inward are sufliciently yielding -to permit the ready insertion and withdrawal of the balls into and from the ring.

I claim asvmy invention 1. A ball retainer formed of sheet metal and comprising a ring formed as a series of cups for engaging theballs, the ring having lips at its respective edges curved into the spaces between the balls and bent transversely, the flat face of the sheet metal forming the inner faces of the lips, the lips being curved so that said. faces conform more or less closely to, and engage the s ides of, the balls.

2. A ball retainer formed of sheet metal and comprising a ring formed as a series ,of cups for inclosing the balls, the ring having lips at its respective edges curved-into the tersely, the edges of theflips practically signed my name in the presence of two meeting, the flat face of the sheet metal subscribing Witnesses.
